BACKGROUND

Bottled beverages, including water, soda, and juices, comprise a multibillion dollar industry worldwide. The primary container used for the storage and sale of such beverages is the plastic bottle. Plastic bottles have gained such widespread use for a variety of factors, including low cost, light weight, ease of use, and durability. Plastic bottles are usually closed at the top with a plastic cap, usually with a type of safety seal. The cap can be removed by twisting or flipping to expose the beverage inside the bottle. Often such caps comprise a movable valve such as a sports bottle cap, which allows a person to seal the bottle and to use the valve as a drinking aid similar to a straw.

Water-soluble drink mixes are in widespread commercial use. Often in tablet or powder form, these mixes allow consumers to create beverages by simply adding water. The consumer measures the indicated or desired amount of mix to water in order to produce a beverage. Such mixing is impractical with common plastic water bottles, as it is difficult to introduce a powder through a narrow opening. It may be easier to do this in the home (with the use of a small funnel), however, but it is quite difficult when traveling or during outdoor activities such as hiking. Furthermore, such “on the go” mixing requires that the consumer carry a separate bottle and drink mix. It is also easy to incorrectly measure the amount of water or drink mix and thus create a beverage that is either too concentrated or diluted.

It is well known in the art that beverage additives such as vitamins, nutrients, and other supplements are volatile when suspended in liquids such as water. The potency of such beverage additives decreases over time in water. As a result, beverage manufactures must “over fortify” such beverages by adding additional vitamins, nutrients, and other supplements to ensure a minimum potency level at consumption or expiration. This causes additional raw material expenses for beverage producers, significantly shortens beverage shelf life, and leaves consumers uncertain of the potency or nutritional value of such beverages.

The general concept of a bottle or container top comprising a storage reservoir for a beverage additive is well known in the art. Various means have been described in the art. However some can suffer from one or more undesirable aspects.

DETAILED DESCRIPTION

The present technology relates to an apparatus, system, and method for making the same related to a cap. Each apparatus, system and method may include one or more embodiments in any combination. The features of any embodiment may be used in combination with any other embodiment. Furthermore, use of the term “top” and “bottom” is not intended to limit the orientation of any element(s), but is only used for convenience of discussion.

An embodiment of the present technology relates to a reservoir compartment bottle cap, which may be referred to as a reservoir cap. As illustrated in FIGS. 1A-1D, the bottle cap is preferably comprised of a first part 70 and a second part 5 which are configured to interlockingly fit together. The first and second parts 70 and 5 may be hollow. As shown in FIG. 1A, the first part 70 may be a top piece 70 and the second part 5 may be a bottom piece 5. The bottom piece 5 may include a chamber 16 for receiving the top piece 70, a bottom seal 25 (also referred to as a punchable seal 25), a surface for securing to a screw top container, a screw top seal, and/or a lock seal. The top piece 70 may include a first hollow part or reservoir 10 for receiving and storing beverage additives. The reservoir 10 in the top piece 70 may be of a shape which allows the reservoir 10 to function as a piercing element 75 for breaking seals. Both pieces may be comprised of an opaque material which can block all light from spoiling the beverage additives. When the two pieces are fitted together, multiple seals may form to prevent spoilage of the beverage additives due to heat, humidity, air, and other environmental factors. The seals can further prevent the fluid in the bottle from prematurely mixing with the beverage additives. Both pieces may be fabricated from a material such as plastic through an injection mold or similar process. Other materials, including but not limited to polymer resin, paper, glass, rubber, silica, carbon, metal, or a combination of these materials (including plastic), may be utilized to achieve the benefits of the writing.

In some embodiments, the piercing member 75 and the bottom seal 25 are configured such that rotating the top piece 70 and the bottom piece 5 with respect to each other causes the piercing member 75 to pierce at least some (or in some embodiments all) of the bottom seal 25. The bottom seal 25 may thus be pierced by the piercing element 75 by a simple rotational or twisting motion, without requiring the top piece 70 to be pushed down into the bottom piece 5. One advantage of such a cap is no additional spatial separator between the top and bottom piece 5 is required to prevent downward movement of the piercing element 75, which would cause premature breaking of the bottom seal 25. This can reduce the amount of material used, and can also eliminate the additional step of removing the spatial separator before pushing the top piece 70 down such that the piercing element 75 breaks the bottom seal 25.

As illustrated in FIG. 2A, in some embodiments, the piercing member 75 may be shaped or arranged such that it does not extend below any of the bottom seal 25 prior to twisting the top and bottom pieces 70 and 5 with respect to each other, but does extend below at least a portion of the bottom seal 25 after twisting as shown in FIGS. 2B and 2C. For example, the piercing element 75 and bottom seal 25 may be configured so that their respective sidewalls have a similar shape such that the piercing element 75 and the bottom seal 25 have a corresponding or matching taper or angle before twisting. For example, the bottom seal 25 can have a taper/angle based on the shape of its sidewall, a taper/angle that is similar to or matches the taper/angle of the piercing element 75 based on the shape of its sidewall. Rotating or twisting the top piece 70 with respect to the bottom piece 5 causes one portion of the sidewall of the piercing element 75 (for example the piercing element 75's longer sidewall) to extend below at least a portion of the bottom seal 25, thereby piercing it. In other embodiments, the taper or angle of the piercing element 75 and bottom seal 25 may not be the same, but rotation of the piercing element 75 nevertheless causes at least one portion of the piercing element 75 to pierce the bottom seal 25.

Alternative piercing techniques using the rotational/twisting caps may be used as well. Additionally, the tapering and angle of the piercing element 75 with respect to the bottom seal 25 may vary, and is not limited to the embodiments or examples depicted herein. Any structure, method and/or system wherein the piercing element 75 pierces the bottom seal upon a rotation or twisting of the top piece 70/piercing element 75 is contemplated.

As illustrated in FIG. 3, at the interface between the top piece 70 and bottom piece 5 may be a locking mechanism such as a save lock 55, which prevents the interlocked top piece 70 and bottom piece 5 from inadvertently moving with respect to each other, absent the application of a force or before the twisting/rotation. For example, the save lock feature may prevent the top piece 70 and bottom piece 5 from rotating with respect to each other until a user applies a twisting motion to break or release the locking mechanism, whereupon the top and bottom piece 5 are no longer locked together by the locking mechanism. The rotational or twisting motion may be applied to either cap.

In some embodiments, the locking mechanism may include one or more releasable or breakable “teeth” that connect the top and bottom piece 5 with each other, thereby preventing their free rotation with respect to each other. Upon application of a sufficient twisting force, the one or more “teeth” are released or broken, so that the locking mechanism no longer prevents the top piece 70 and bottom piece 5 from rotating with respect to each other.

In some embodiments, the bottom seal 25 does not require a line of weakness. In other words, the bottom seal 25 may have a relative uniform strength/material across its entirety, and yet still be pierced by the hollow piercing element 75.

As shown in FIG. 1A, in some embodiments, the top piece 70 includes a first sidewall 12 and second side wall 14 of different lengths, thereby creating a tapered or angular circular edge 100 at the bottom of the piercing element 75. For example, top piece 70 as represented in FIG. 1A represents a cutaway view of the top piece 70, and FIG. 1B depicts the exterior view of the top piece 70. Top piece 70 comprises a hollow piercing element 75, which is formed by exterior wall 80, and has an angled circular edge 100 at the bottom of piercing element 75. Angled circular edge 100 is at an angle of inclination such that, when the save lock 55 is released or broken by a twisting motion of the top piece 70, for example, and top piece 70 is rotated with respect to bottom piece 5, the angled circular edge 100 breaks through and at least partially (or entirely) pierces and opens bottom seal 25.

In some embodiments, completely rotating the top and bottom pieces with respect to each other does not cause the bottom seal 25 to completely separate from the bottom portion because of the taper/shape of both the piercing element 75 and the bottom seal 25. In such embodiments, as the piercing element 75 approaches its initial position, it no longer extends below the bottom seal 25 due to its matching taper with the bottom seal 25. Thus, as the piercing element 75 approaches its initial position, it does not pierce that portion of the bottom seal 25. This allows the bottom seal 25 to remain at least partially attached to the bottom portion, thereby preventing it from falling into the container.

The amount of rotation or twisting necessary to break the bottom seal 25 can vary, and is not limited to a particular amount in any way. For example, the seal-breaking rotation may be 90 degrees, 180 degrees or 340 degrees. Alternatively, the seal-breaking rotation can be anywhere from 1 degree to 360 degrees.

In some embodiments, the amount of rotation after releasing the locking mechanism may be limited by another structural feature on the top and/or bottom piece 5. Such a structure may inhibit rotation of the top piece 70 with respect to the bottom piece 5 after beyond a certain amount even after releasing the locking mechanism. In other embodiments, no such rotation-limiting structures are present or required so that the top and bottom piece 5 may rotate freely with respect to each other after releasing the locking mechanism.

In some embodiments, the bottom piece 5 also includes a separate locking mechanism such as a save lock for preventing inadvertent rotation of the bottom piece 5 with respect to the container to which it may be connected. This save lock 55 mechanism may also include the one or more “teeth” described previously. Upon rotation of the bottom piece 5 with respect to the container, the save lock 55 mechanism is released, for example by breaking or releasing the “teeth”, thereby permitting free rotation of the bottom piece 5 with respect to the container.

In some embodiments, bottom piece 5 further comprises exterior wall or protrusion 48, which with rings or threads 35, enables bottle cap 1 to screw onto bottle 160. Top piece 70 can also comprise a protrusion 18.
